Thank you guys all so much for your support. Turns out it was this lil guy here. 1300-2 Nartron RELAY
I am fortunate enough to be in contact with the mechanic who used to work on this exact bus from the school district. He has been working on crowns for years and said pretty much the same thing some of you did.
He said most of the time it is the neutral safety switch, and to check the one under the hatch above the engine. Though then he told me to try using the neutral by pass button to override it which did not work. I then sent him the picture above as he could not remember what the starting array looked like. He then told me to take that green wire on the solenoid that goes up to the relay and just ground that out.
This worked like a charm it started right up, though now I have no neutral safety and that switch is $180. Good news is he told me that if I just take that green wire and bond it to the next wire to the right of on that relay (that wire goes to the alternator), that I could achieve neutral safety that way. Apparently that was how they used to do it before they incorporated that relay.
I will test this out tomorrow or the next day and get back to you.
Thanks again Nat roadrunner and cowlitz for your lengthy responses, cowlitz you were pretty on point with that, did you used to work on crowns?
